【摘要】 目的 观察窄谱中波紫外线联合复方甘草酸苷治疗寻常性银屑病的疗效。 方法 2007年2月—2010年11月，将收治的126例银屑病患者随机分为治疗组和对照组，治疗组72例采用注射复方甘草酸苷与窄谱中波紫外线联合治疗，对照组54例则仅采用窄谱中波紫外线治疗，以银屑病皮损面积和疗效指数（PASI）评价对比两组疗效。 结果 两组治疗后PASI评分均明显低于治疗前；治疗后治疗组PASI评分低于对照组，且差异有统计学意义（Plt;0.05）；两组治疗有效率分别为87.5%和79.6%，治疗组疗效明显优于对照组（Plt;0.05）。 结论 窄谱中波紫外线与复方甘草酸苷联合治疗寻常性银屑病，不良反应小，治愈率高，值得临床推广。【Abstract】 Objective To observe the clinical efficacy of compound glycyrrhizin combined with narrow-band ultraviolet B (NB-UVB) in treating patients with psoriasis vulgaris. Methods A total of 126 patients with psoriasis vulgaris treated in our hospital from February 2007 to November 2010 were randomly divided into the treatment group and the control group. Seventy-two patients in the treatment group were treated with NB-UVB radiotherapy combined with compound glycyrrhizin, and 54 patients in the control group were treated with NB-UVB radiotherapy alone. The curative effects were evaluated in terms of the area of injury and therapeutic effect indexes. Results The PASI score after treatment for both groups was obviously lower than before, and the score of the treatment group was significantly lower than the control group after treatment. The efficacy rate was respectively 87.5% and 79.6% for the treatment group and the control group, with a significant difference (Plt;0.05). Conclusion NB-UVB combined with compound glycyrrhizin is safe and effective in treating psoriasis vulgaris, and it is worth popularizing.
